In order to solve the above problems, the utility model provides an audio mixing device for long-distance wireless transmission, including a bluetooth transmitting module, an audio transmitting module, an audio mixing transmitter and a receiver; The audio mixing transmitter is connected to the receiver; the audio mixing transmitter includes a Bluetooth receiving module, an audio mixing module and a transmitting module; the Bluetooth receiving module, an audio mixing module and a transmitting module are connected in sequence, and the transmitting module is connected to the receiver ; Bluetooth transmitting module and audio transmitting module, after receiving the signal, the audio mixing transmitter performs audio mixing, and then the transmitting module inside the audio mixing transmitter sends it to the receiver for subsequent processing.

Optionally, there is a wireless connection between the transmitter module and the receiver. Through wireless connection, redundant wire connections are reduced, and FM, VHF, UHF or 2.4G transmission technology is used, which can increase the transmission distance and cover various places in small and medium occasions. corner.

Optionally, there is a wireless connection between the Bluetooth transmitter module and the Bluetooth receiver module. Since the audio mixing transmitter is portable, it can ensure that the distance between the Bluetooth transmitter module and the Bluetooth receiver module is relatively close, making the Bluetooth transmission more stable.

Optionally, the audio transmitting module and the audio mixing module are connected wirelessly or with wires, and the audio transmitting module can be connected with the audio mixing transmitter in a wired or wireless manner to ensure that the audio can be transmitted without distortion.

Optionally, an audio amplifier and a speaker are also included, the receiver is connected to the audio amplifier, the audio amplifier is connected to the speaker, and finally the audio volume is boosted by the audio amplifier and played through the speaker.

Compared with the prior art, the utility model has the following beneficial effects:

By embedding the Bluetooth receiving module into the audio mixing transmitter, the audio mixing transmitter and Bluetooth player (such as a smart phone) can be carried or used nearby. The audio mixing transmitter adopts FM, VHF, UHF or 2.4G to support long-distance Transmission technology, long-distance transmission of audio and Bluetooth mixed information to the receiver, the receiver is connected to the post-stage amplifier equipment, so as to realize the mixing and long-distance transmission of Bluetooth and audio signals.
